Скачать или смотреть Why Small Samples Fool Us: The Law of Small Numbers Explained

Have you ever made a sweeping judgment based on just a few reviews, a couple of conversations, or one bad experience? It's a universal human tendency, and it's rooted in powerful cognitive biases that cause us to draw big conclusions from statistically tiny samples.

In this video, we explore the psychology behind why our brains are so bad at dealing with sample size. We'll dive into an analysis of academic research that reveals the key mental shortcuts responsible for these errors in statistical reasoning.

You'll learn about two of the biggest culprits:
1. *The Law of Small Numbers:* The mistaken belief that a small sample will perfectly reflect the entire population.
2. *The Representativeness Heuristic:* Our tendency to judge situations based on how closely they match our mental prototypes, ignoring statistical probability.

We'll also look at fascinating research findings, including how people's confidence in a conclusion often plateaus after seeing a sample size of just thirty, and how these biases affect everyone—from the general public to trained experts.

From the gambler's fallacy to optimism bias, discover the persistent cognitive shortcuts that undermine our ability to think statistically and learn how to become a more critical thinker.
